In this application, work as whole car network is right after the battery is accomplished and is once charged, can return the execution and pass through battery monitoring devices monitors whether the step of the condition of charging is satisfied to the battery, and it is right to continue monitoring the battery realizes closed-loop control, right the battery carries out the control of not stopping, can in time react when the battery needs to charge, improves the user and uses car experience.
In an embodiment of the application, after the whole vehicle control device wakes up a whole vehicle network, the electric quantity information of the storage battery is pushed to a user.
Fig. 5 shows a schematic diagram of a path for pushing the information of the charge amount of the storage battery to a user in an embodiment of the present application. In this application, for making the user in time receive the message that the electric automobile battery has the emergence insufficient voltage risk the timely propelling movement electric quantity information after whole car network is activated can let the user in time discover that there is the on-vehicle equipment not normally to close. The push path may be a whole electric vehicle network 501, a cloud server 502, a user mobile phone 503, and the cloud server 502 may send the user mobile phone 503 through an application program or a short message. For example, a user a has an electric vehicle B, when the user a finishes using the vehicle, the user forgets to turn off an in-vehicle reading lamp of the user B, the in-vehicle reading lamp continuously consumes the electric quantity of a storage battery of the user B, and the user B finally wakes up the entire vehicle network and sends information to the user a after internal monitoring, so as to remind the user a that the vehicle-mounted device may not be turned off. A can return to B and turn off the reading lamp in the vehicle, thereby avoiding the situation of insufficient power of the storage battery.
In order that those skilled in the art may more fully understand the present teachings, a full range of embodiments is now described.
User A has an electric automobile B, and when A ended the use of the car, forgets to close B's reading lamp in the car, and reading lamp in the car lasts the electric quantity of consuming B's battery, and the inside battery monitoring devices of B monitored out that battery electric quantity has been less than predetermined electric quantity threshold value 60%, then the activation battery monitoring devices with communication circuit between the whole car controlling means is 1 hour through scheduled time battery monitoring devices with after the communication between the whole car controlling means, confirm the battery really needs to charge, then control whole car controlling means activates whole car network, and control carries out high pressure to the vehicle and goes up the electricity, thereby right the battery charges to inform A through cell-phone application with the electric quantity message, thereby avoid the battery that B takes place to lack the electric problem.
